LIGHTING ACCESSORY FOR WICKLESS BURNERS OR STOVES.

Application filed January 30, 1923. Serial No. 615,906.

To all whom it may concern:

Be it known that I, BENJAMIN BARK, a subject of the King of GreatBritain, residing at Isleworth, Middlesex, England, have invented a newand useful Improvement in Ligl'iting Accessories for VVickless Burnersor Stoves, of which the following is aspecification.

This invention relates to wickless burners or stoves for consumingpetroleum, or other suitable liquid fuel, of the kind wherein there isan annular cup, which is normally heated by means of flames produced bythe combustion of part of the gaseous combus tible mixture used forsupplying the main flame.

According to my invention, there is provided a tubular member, the baseof which is adapted to rest in the cup before mentioned and the upperpart of which is made with an aperture through which issues the gaseousmixture for forming the main flame. This main flame is used for heatingan incandescent mantle which may be advantageously supported on saidtubular member in any suitable manner, e. g. by means of a forked stick.Around the base of the tubular member, there is formed a series of smallperforations which permit a small portion of the gaseous mixture to passout and form flames for heating the cup and connected parts, e. g. thevaporizing tube or nozzle of the burner.

By this means, any oil vapour or like burner having an annular cup asabove mentioned and primarily designed for cooking or other heatingpurposes, may be conveniently used for lighting purposes, all that isnecessary being to place the tubular member in position in the cup.

In the accompanying drawing 2- Figure 1 is a vertical central section,and

Figure 2 a plan showing my improved device applied to a vapour burner ofthe cup type and adapted for heating a mantle for lighting byincandescence. I

A. is the cup of a burner of a known type, wherein a vaporizing tube andvapour nozzle B are heated by conduction from the cup which is itselfheated by flames issuing from perforations in the side wall of themixing chamber C, that has within it the air injector tube D.

On the floor A of the cup A, there rests the lower end of a tubularchamber which has a cylindrical wall E and is open at the bottom. Thischamber has a domed top F, in the centre of which there is mounted theinlet G of a tubular burner head H of a known type having a wire gauzetop J and socket K supported by an internal spider for receiving themantle stick L.

The lower part of the cylindrical wall is provided with an annularseries of holes M, M through which some of the gaseous mixture from themixing chamber C passes out and forms a series of flames to heat the cupA and connected parts. The major part of the combustible -mixture passesup through the inlet G of the burner head where it is used in the knownmanner for heating the mantle. N is an annular deflecting ring for theproducts of combustion from the flames in the cup A. This deflectorprevents these products of combustion from clinging to the exteriorsurfaces of the chamber E, F and burner head and so preventing freeaccess of air to the main flame heating the mantle.

The tubular member may be provided with a loop, such as O, or the like,on its exterior face so that when not required for use it may be liftedoff by means of a key, or the like, constructed to engage within theloop, so that the tubular member can be lifted from the burner.

It is obvious that the form of the improved device may be varied withoutdeparting from the nature of my invention, for example the chamber E, Fmay be made hemispherical or conical instead of cylindrical with a domedtop. Moreover the burner head H, J, K may be any other suitable knownform. m

What I claim is z An accessory for a wickless burner of the typeembodying a heated annular cup, said accessory comprising a tubularmember having an open lower end adapted to rest in the annular cup ofthe burner and having a series of apertures adjacent its lower end, agas deflecting ring surrounding said tubular member, a connection pieceextending upwardly from said tubular member, and a burner head carriedby said connection piece.
